CHARLIE R. EDMONDS Patented Feb. 24, 1953 UNITED STATES PATENT OFFICE 2,629,600 MARKER, TYPE ritoJEoTILE "Charlie R. 'Edinonds, Cincinnati, Ohio Application member 24, 1960, "SerialNo. 1 97, 3 7 7 '5 caring. (01. 273-406) This invention relates to a projectile and more particularly to a projectile having fa detachable marker elementsecured thereto for detachment therefrom upon impact.

An object of the invention is to provide a projectile in the form of an arro'w c'asting plug, or the like having a detachable head, indicator element jor landing marker releasably secured thereto in such a manner as to be automatically disconnected from the projectile incident, to, the landing impact of the projectile at the end of its flight.

Another object of the invention is to provide a projectile having the hereinabove. described characteristics which may be utilized for accurately indicating the place ofgim'pact of a projectile, and which may be simply yet effectively re-secured to the projectile without requiring the use of special equipment or tools.

A further object of the invention is to provide a projectile, and in particular a casting plug which is particularly adapted for ldry casting, that is, for making practice casts upon the ground, the detachablehead enabling the user of the device to clearly ascertain the locus of impact of the plug. v

Still a further object of the invention is to provide a casting plug the forward end of which is provided withmeans for facilitating the attachment of complementary dome shaped markers which will be automatically disengaged from the plug incident to impact thereof on said marker at the end of its free flight. The casting plug may then be retrieved by means of a reel or other suitable device, after which another marker member may be associated with the for ward end of the plug for another cast. In this manner I have provided simple, inexpensive, yet highly effective means for enabling a caster to make 'a plurality or casts with a plug and have accurate means for indicating the place of initial impact of the plug on each of the various out'prbmngd periods of time an though atjected to rough handling and usage. to which such equipment is subjected when used by the public at large.

,These and other objects are attained by the means described herein and as disclosed in the accompanying drawings, in which I Fig. 1 isaside elevational view of a casting plug embodying the teachings of the present invention,

, Fig. 2 is a vertical section through the casting plug of Fig. 1.

Fig. 3 is a view of the forward portion of the device of Fig. 2 illustrating the relative relationship between the detachable marker member and, the body of a projectile just after impact at the end of free flight of the projectile, andillustrating a phase inv the, process of disengagement of the marker therefrom.

Fig. 5 is a side elevational view of amodified type of detachable head, indicator element or landing marker comprising a detail of the present invention. I

Fig. 6 is a front elevational view of the deviceof Fig. 5. With particular reference now to Figs. 1 and 2, the numeral ill denotes a projectile in the form of a casting plug comprising an elongate body portion H, as best illustrated in Fig. 2. The body portion terminates in a weighed forward end [2, the rear vend H being provided with an eyelet l6 for facilitating attachment of the plug to the end of a length of line.

In the preferred embodiment of the invention a substantially hollow dome-like landing marker 2015 provided for loosely receiving the forward end of the plugbody wherein the inner face 22 of the side wall portion I 24 of the marker is disposed in spaced relationship with adjacent portions of'the forward end of the lure.

Suitable means, such as, by way of example, a two-element fastener, may be utilized for releasably securing marker 29 to the forward portion of the lure.

In Figs. 2 and 3 one element 24 of a two-element fastener assembly is secured to and carried by front edge 26 of forward end I2, such as, by way of example, by means of a rivet '28. The other element 30 of the two-element fastener assembly is secured to and carried by the central portion of the inner face 32 of dome 29 such as, by way of example, by means of a rivet 34.

I as illustrated in Fig. 2, snap ring 35 is disposed around the outer inclined face of plug 24 and dome 20 will be securely though releasably fastened to the forward end of plug body In wherein a normal to a tangent plane through top 40 of the dome will be disposed in substantial axial alignment with the longitudinal axis of body I I.

The dome will thus be securely, though detachably, fastened to the body portion whereby to remain thereon incident to all phases of a casting operation. However, when the plug lands upon a supporting surface indicated generally by the numeral 52 in Fig. 3, it will land upon head 20 which will be cocked or moved out of axial alignment with body H with the result that peripheral edge 54 of the dome will be moved or shifted toward the body portion, thereby effecting disengagement of fastener elements 24 and 30 incident to movement of snap ring 35 off plug 24. Head or marker 20 will be released from the plug thereby accurately indicating the locus of impact of the plug with supporting surface 52. The plug may then be suitably retrieved and another domed marker member associated with fastener element 24 of the plug, thereby enabling the caster to accurately mark the location of impact of a plurality of casts. Or, if desired, a golf type of game may be played wherein each player will have one plug and one marker head of a color different from the color of the mar er heads of the other players. Instead of driving a golf ball. each player casts a plug and the locus of contact of the various plugs will be marked by the various marker heads. After each cast the players may reel in their respective plugs, thereby preparing for their next cast which will be made when they reach their respective head markers which will be attached to their lugs for the next cast.

In the preferred embodiment of the invention a peripheral rim 6!) is provided adjacent and in circumscribing relationship with the rear or open end of dome 20 for therebv augmenting or emphasizing the cocking of the marker relative to the body portion incident to impact of the projectile.

With reference now to Figs. and 6, domed markers 20 have been provided with a forwardly extending fin portion 10 the forward end 12 of which extends forwardly beyond top 40 of the dome by a dimension indicated by the numeral 14. This construction insures positive detachment of marker even in those instances wherein the projectile lands vertically upon a supporting surface. But for fin 10, a vertical impact would fail to shift or cook the peripheral edge of the marker relative to the body portion, however impact of forward edge 12 of fin 10 will result in cooking of the dome marker 20 relative to body l0 thereby insuring positive disengagement therefrom.

In Fig. 4 I have illustrated a marker dome 20 secured to the forward or headed porti n .0 f

an arrow 82, it being understood that the structural and functional characteristics of the forward part of head are identical with the functional-and structural characteristics of the casting plug illustrated in Figs. 2 and 3.

If desired, the body portion and detachable marker may be fabricated from any suitable material such as by way of example, the various plastics, however such material is exemplary rather than restrictive, it being understood that other substances such as metal or wood, etc. could be used.

The overall weight and casting characteristics of a casting plug provided with my marker head are identical with the weight and casting characteristics of conventional plugs, thereby greatly enhancing the utility of my device.

It should be understood that various changes and modifications in the structural details of the device may be made, within the scope of the appended claims, without departing from thespirit of the invention.
